Alternation in ST segment appearance ( or in the amount of ST elevation or depression ) — is often linked to ischemia. This may result from fluctuations in heart rate or in nervous system activity or from pharmacologic treatment. Repolarization Alternans — entails beat-to-beat variation in the ST segment and/or T wave.

If the rhythm converts and then reverts to tachycardia with either adenosine or electricity, Neither one of those modalities should be attempted until some longer acting pharmacological solution is given. WPW does not always have delta waves on the baseline ECG. This is called "Concealed conduction".
